Listen to the Morse code of SOS

SOS is a Morse code distress signal (  ▄ ▄ ▄ ▄▄▄ ▄▄▄ ▄▄▄ ▄ ▄ ▄ ), used internationally, that was originally established for maritime use. In formal notation SOS is written with an overscore line, to indicate that the Morse code equivalents for the individual letters of «SOS» are transmitted as an unbroken sequence of three dots / three dashes / three dots, with no spaces between the letters.[1] In International Morse Code three dots form the letter «S» and three dashes make the letter «O», so «S O S» became a common way to remember the order of the dots and dashes. (IWB, VZE, 3B, and V7 form equivalent sequences, but traditionally SOS is the easiest to remember.)

SOS, when it was first agreed upon by the International Radio Telegraphic Convention in 1906, was merely a distinctive Morse code sequence and was initially not an abbreviation. Later in popular usage it became associated with mnemonic phrases such as «Save Our Souls» and «Save Our Ship».[2] Moreover, due to its high-profile use in emergencies, the phrase «SOS» has entered general usage to informally indicate a crisis or the need for action.

SOS originated in German government maritime radio regulations adopted effective 1 April 1905. It became a worldwide standard when it was included in the service regulations of the first International Radiotelegraph Convention and signed on 3 November 1906, which became effective on 1 July 1908. In modern terminology, SOS is a Morse «procedural signal» or «prosign«,[3] used as a start-of-message mark for transmissions requesting assistance when loss of life or catastrophic loss of property is imminent.[4] Other prefixes are used for mechanical breakdowns, requests for medical assistance, and a relayed distress signal originally sent by another station. SOS remained the maritime radio distress signal until 1999, when it was replaced by the Global Maritime Distress and Safety System.[5]

SOS is still recognized as a standard distress signal that may be used with any signaling method.[6] It has been used as a visual distress signal, consisting of three short/three long/three short flashes of light,[7] such as from a survival mirror. In some cases the individual letters «S O S» have been spelled out, for example, stamped in a snowbank or formed out of logs on a beach. «S O S» being readable upside down as well as right side up (as an ambigram) is an advantage for visual recognition.

History[edit]

SOS was introduced for emergency maritime radio communication using Morse code.

Radio (initially known as «wireless telegraphy») was developed in the late 1890s, and was quickly recognized as an important aid to maritime communication. Previously seagoing vessels had adopted a variety of standardized visual and audio distress signals, using such things as semaphore flags, signal flares, bells, and foghorns. However, initially cooperation in standardizing radio distress signals was limited by national differences and rivalries between competing radio companies.

In 1903, an Italian representative at the Berlin Preliminary Conference on Wireless Telegraphy, Captain Quintino Bonomo, discussed the need for common operating procedures, including the suggestion that «ships in distress… should send the signal SSS DDD at intervals of a few minutes».[8] However, procedural questions were beyond the scope of this conference, so no standard signal was adopted at the time, although Article IV of conference’s Final Protocol stated that «Wireless telegraph stations should, unless practically impossible, give priority to calls for help received from ships at sea».[9]

In the absence of international regulations, individual organizations were left to develop their own practices. On 7 January 1904 the Marconi International Marine Communication Company issued «Circular 57», which specified that, for the company’s worldwide installations, beginning 1 February 1904 «the call to be given by ships in distress or in any way requiring assistance shall be ‘C.Q.D.’«.[10] An alternative proposal, put forward in 1906 by the U.S. Navy, suggested that the International Code of Signals flag signals should be adopted for radio use, including «NC», which stood for «In distress; want immediate assistance».[11]

Germany was the first country to adopt the SOS distress signal, which it called the Notzeichen signal, as one of three Morse code sequences included in national radio regulations which became effective on 1 April 1905.[12][13] In 1906, the first International Radiotelegraph Convention met in Berlin, which produced an agreement signed on 3 November 1906 that become effective on 1 July 1908. The convention adopted an extensive collection of Service Regulations, including Article XVI, which read: «Ships in distress shall use the following signal:   ▄ ▄ ▄ ▄▄▄ ▄▄▄ ▄▄▄ ▄ ▄ ▄  repeated at brief intervals».[14]

Cunard liner RMS Slavonia photographed the day it was wrecked on 10 June 1909; it is the earliest-reported ship to have transmitted the SOS distress call.

In both the 1 April 1905 German law and the 1906 international regulations, the distress signal is specified as a continuous Morse code sequence of three dots / three dashes / three dots, with no mention of any alphabetic equivalents. However, in International Morse, three dots comprise the letter «S», and three dashes the letter «O», and it soon became common to informally refer to the distress signal as «S O S», with the 12 January 1907 Electrical World stating that «Vessels in distress use the special signal, SOS, repeated at short intervals.»[15] (In American Morse code, which was used by many coastal ships in the United States through the first part of the twentieth century, three dashes stood for the numeral «5», so in a few cases the distress signal was informally referred to as «S 5 S».)[16]

The first ships that have been reported to have transmitted an SOS distress call were the Cunard liner RMS Slavonia on 10 June 1909 while sailing the Azores,[17][18] and the steamer SS Arapahoe on 11 August 1909 while off the North Carolina coast.[19][20] The signal of the Arapahoe was received by the United Wireless Telegraph Company station at Hatteras, North Carolina, and forwarded to the steamer company’s offices.[21] However, there was some resistance among Marconi operators to adopting the new signal, and as late as the April 1912 sinking of the RMS Titanic the ship’s Marconi operators intermixed CQD and SOS distress calls. In the interests of consistency and water safety, the use of CQD appears to have died out thereafter.

Later developments[edit]

Additional warning and distress signals followed the introduction of SOS. On 20 January 1914, the London International Convention on Safety of Life at Sea adopted as the «Safety Signal» the Morse code sequence «TTT»   ▄▄▄   ▄▄▄   ▄▄▄  (three «T’s» (  ▄▄▄ ))—spaced normally as three letters so as not to be confused with the three dashes of the letter O (  ▄▄▄ ▄▄▄ ▄▄▄ )—and used for messages to ships «involving safety of navigation and being of an urgent character».[22]

«Mayday» voice code[edit]

With the development of audio radio transmitters, there was a need for a spoken distress phrase, and «Mayday» (from French m’aider «help me») was adopted by the 1927 International Radio Convention as the spoken equivalent of SOS.[23] For «TTT», the equivalent spoken signal is «Sécurité» (from French sécurité «safety») for navigational safety, while «Pan-pan» (from French panne «breakdown»; Morse «XXX») signals an urgent but not immediately dangerous situation.[24] French was the international language at the time that these were formalized.

World War II suffix codes[edit]

During World War II, additional codes were employed to include immediate details about attacks by enemy vessels, especially in the Battle of the Atlantic. The signal «SSS» signaled attacked by submarines, while «RRR» warned of an attack by a surface raider, «QQQ» warned of an unknown raider (usually an auxiliary cruiser), and «AAA» indicated an attack by aircraft. They were usually sent in conjunction with the SOS distress signal. All of these codes later switched from three repeats of the letter to four repeats, e.g., «RRRR».

None of these signals was used on its own. Sending SOS as well as the urgency signal («XXX» in CW, and «PAN-PAN» in voice)[25] and safety signal («TTT» in CW, and «SECURITE» in voice)[26] used similar procedures for effectiveness. These were always followed correctly. Following is a hypothetical example of an SOS signal; the portions in parentheses are an explanation only.

SOS SOS SOS (urgent distress call follows)

DE (from) GBTT GBTT GBTT (GBTT identifies the Queen Elizabeth 2 radio room, repeated 3 times)
(Ship) QUEEN ELIZABETH 2 PSN (position) 49 06 30 N (North latitude) 04 30 20 W (West longitude)
(Our ship is) ON FIRE (and the crew is) ABANDONING SHIP

AR (End of Message) K (reply, anyone)

Audio tone signals and automatic alarms[edit]

Ships and coastal stations would normally have required quiet times twice an hour to listen for priority signals, for 3 minutes, at different times for 500 kHz and 2182 kHz.

Ship's radio room clock

Ship’s radio room clock, with 4-second-long red bands with 1-second white gaps around the circumference, so the CW alarm signal could be sent manually. The red and green wedges denote compulsory 3-minute silent periods for receiving weak distress signals.

Since many merchant vessels carried only one or two radio operators, no one might hear a distress signal when both operators were off-duty. Eventually, equipment was invented to summon operators by ringing an alarm in the operator’s cabin, and on the bridge, and the only switch able to disable the alarm was only permitted to be in the wireless telegraph room.[27] The alarm was sent by the operator on the ship in distress transmitting the radiotelegraph alarm signal (auto-alarm) signal—twelve extra-long dashes, each lasting four seconds with a one-second gap between them, and transmitted in A2 (modulated CW).[28] The alarm signal was normally sent with a mechanical or electronic timing circuit to ensure it was sent accurately. However, ships radio room clocks typically had markings on the dial to guide operators in sending the signal manually. The regulations for the auto-alarm were defined in the 1927 Safety of Life at Sea (SOLAS) international maritime regulations, and in Article 19, § 21, of the General Regulations annexed to the International Radiotelegraph Convention, 1927.5 5.[27]

The Auto Alarm receivers were designed to activate upon receiving four such dashes. Once four valid dashes are detected, the automatic alarm is activated. The distressed ship’s operator would then delay sending the SOS message itself to give off-watch radio operators time to reach their radio room.

The radiotelephony equivalent of the radiotelegraph alarm signal is the radiotelephony alarm signal, which is the transmission of alternating tones of 2200 Hz and 1300 Hz, with each tone having a duration of 250 ms. Automatic alarm systems aboard ships must activate when such a signal is received and the receiving vessel is within 500 nmi (930 km) of the transmitting vessel’s position, or if the distress position is in the polar areas (latitude greater than 70° N or 70° S). The alarm should also activate when the call is received and the distance between the vessel in distress and the receiving vessel cannot be determined.[29]

MORE ABOUT SOS

What does SOS mean?

The letter sequence SOS (pronounced S-O-S) is used in Morse code as a distress signal—a way to call for help during an emergency, such as on a ship.

Morse code uses clicks and pauses, short and long sounds, or flashes of light to represent letters and numbers. S is represented by three short clicks or brief flashes of light, and O is represented by three long sounds or longer flashes of light (depicted with dashes).

Morse code can be written out using dots to represent short clicks and dashes to represent long ones, resulting in a specific sequence for SOS (··· – – – ···) that was chosen since it would be easy to communicate with sounds over radio or with flashes of light.

The signal became well-known enough that SOS came to be used as an informal term for any call for help or notification that there is an emergency, as in Send an SOS to the board letting them know that we’ll have to schedule an emergency meeting. 

When used this way, each letter is still pronounced individually (S-O-S). The plural of SOS can be written as SOSs or SOS’s. SOS can also be used as a verb meaning to send such an SOS.

Example: I have my phone set up to automatically send an SOS to certain contacts if I ever dial 9-1-1.

Where does SOS come from?

SOS was officially designated as a distress call in the early 1900s. Contrary to popular belief, the sequence SOS was not meant to stand for “save our ship” or “save our souls,” both of which were applied to the series of letters later. In fact, the letters were not intended to stand for anything—they were chosen simply because they are easy to communicate in Morse code and the resulting sequence is easy to distinguish from any other message.

Morse code has since largely fallen out of practical use in favor of systems based on more advanced technologies, especially satellite communication. However, use of the term SOS as an informal way of referring to a distress call is still common.

Did you know … ?

How is SOS used in real life?

The signal SOS was once commonly used in the context of radio communication among ships. Today, the use of SOS as a general way to refer to a call for help is informal. It’s sometimes used in situations that aren’t quite emergencies—you might text an SOS to your roommate to bring home ice cream, for example.

At 12.57am, the first use of ‘SOS’ by the Titanic is recorded. According to Harold Bride, he had asked Phillips what he was sending and was told ‘CQD.’ Appealing to his sense of humour, Bride suggested using the new call, ‘SOS’, as it may be his last chance to send it. pic.twitter.com/4qvtqbQMep
